Hydrex: Hydrex permanent welding repairs include the following operations:
Renewal of damaged hull plating, large or small areas
Crack repairs by use of cofferdam
Pipe/flange repairs or replacements
Clad welding of cavitated areas
Inwater seachest installation
These operations are carried out afloat with the use of an external cofferdam. In most cases normal commercial activities can therefore continue without disruption. We have a wide range of standard cofferdams available at our offices, but a tailor-made cofferdam can also be created to fit a specific hull shape.
